Terminals 5 of a connector 4 are mounted on the lands 3. The connector 4 is electrically and mechanically connected to the circuit board 1 by applying the solder 6 in the placed state and soldering the land 3 and the terminal 5.

When the contact is made, the actual operation can be checked without inserting and removing the mating connector from the connector, so that the checking operation can be easily performed. In addition, when such a connector mounting structure is employed, it is likely that the common terminal of the connector is not properly soldered to both the first land and the second land. Incomplete soldering that may cause poor conduction is easily found.

A second land 8 and a third land 9 derived from the second land 8 and located outside the mounting area of the connector 4 are formed. Solder 6 is applied in a state where connector terminals 5 are mounted on 7, 8 and solders are applied to lands 7, 8 and terminals 5, respectively, so that connector 4 is electrically and electrically connected to circuit board 1. Mechanically connected. Here, the third land 9 derived from the second land 8 is for performing an electrical test using the probe 11 or the like.
The method of soldering the connector terminals 5 on the first and second lands 7 and 8 is to apply the solder 6 on each of the lands 7 and 8 and then place the connector terminals 5 thereon. It may be attached.

ク作業が遂行できる。The connector 4 mounted with the connector terminals 5 soldered to the first and second lands 7 and 8 as described above requires an internal circuit as long as the connection with the first lands 7 is ensured. It does not hinder conduction with the pattern 2, but if it is also connected to the second land 8, the connection between the internal circuit pattern 2 and the third land 9 for the probe 11 is established via the connector terminal 5. Can be kept. Therefore, the circuit board 1 is connected via the connector 4 thus mounted.
When a probe 11 is brought into contact with a third land 9 derived from the second land 8 when performing an operation check of, for example, a liquid crystal display device connected to the internal circuit pattern. It is possible to check whether the output is correct from the connector 2, and it is not necessary to insert and remove the mating connector from the connector 4. As a result, complicated insertion / removal work is eliminated and the number of steps is reduced, so that the check work can be performed extremely easily.

る。When such a connector mounting structure is employed, if the connector terminal 5 is not securely soldered to both the first land 7 and the second land 8, it is easy to determine that the connector terminal 5 is unsuitable during an electrical inspection. Therefore, there is an advantage that it is easy to find incomplete soldering that causes conduction failure at a later date, and thus the reliability of the actual operation check is increased.
